TUCSON, Ariz. (13 News) - Tucson residents might see smoke from the annual controlled burn at the Sweetwater Wetlands.

The burn started this morning, November 6.

The area will remain closed until November 9.

Since 1999, Tucson Water and the Tucson Fire Department have collaborated on the annual controlled burn.

The effort not only supports Tucson Water’s Mosquito Abatement Program but also provides training for regional wildlands firefighters and helps manage invasive plant species.

This year’s burn was scheduled to allow for the regeneration of native habitats in time for the winter migratory bird season.
